Carbon capture

Once famous for building the world's biggest and most powerful engines, Finnish company Wärtsilä is investing heavily in technology to clean up the notoriously difficult heavy marine sector. CEO Håkan Agnevall lays out a roadmap to zero carbon 2050.

A consortium of researchers from four European countries is developing a way to tattoo microbes on the exterior of buildings. These "living tattoos" will be able to suck carbon out of the air, protect the buildings, and even make them glow.

Transporting goods on huge fossil-fueled cargo ships is a dirty business. But one such vessel is about to embark on a pilot that could clean up shipping's act considerably. An onboard system has now been installed on the Clipper Eris that will capture CO2 from its exhaust outlets and store it in tanks.

Using principles from rocket science, researchers have created carbon with a record-breaking surface area. The material can soak up about twice the amount of CO2 as current activated carbon materials and has impressive energy-storage capabilities.

A new material tackles the carbon problem of concrete production and usage by employing a pretty unusual workforce: cyanobacteria. The bio-cement these micro-organisms help to produce harnesses a process that's existed in nature for 3.5 billion years.

The production of concrete is a major contributor to worldwide CO2 emissions, however Nendo showcases a greener alternative with its Block-Wall House, which was part-built using a novel concrete that actually captures carbon-dioxide.

The world’s largest ocean-based carbon dioxide removal plant is being built in Singapore, and will be capable of capturing 8 million lb of CO2 per year while also producing 231,000 lb of carbon-negative hydrogen.

A remarkable pilot project installed on a 240-m (787-ft) container ship has proven it's possible to capture at least 78% of emissions from the smokestacks of cargo ships and convert the CO2 into limestone pebbles, which can be offloaded and sold.

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists employing a smart dual-method process.

Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity.

Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.

A student team has built a prototype electric passenger car that removes and stores carbon dioxide from the air as it rolls down the road, with the aim of capturing more CO2 than is emitted during the full lifecycle of the vehicle.
